I have this jersey. The arms are long enough for me in a medium, I wish the zipper was longer. I've worn it in the high 70s, low 80s mountain biking and it was fine. I'd like to be able to vent the front more.


I'm a lot more comfortable in my regular jerseys, with long zippers, and arm coolers though. I haven't been out in our super heat yet - just the mid 80s.
